Chapter 1: Introducing Physics (2 of 6) The Two Important Foundational Principles of Learning:

Chapter 1: Introducing Physics (2 of 6) The Two Important Foundational Principles of Learning: 1. Learning is a physics process: No one can learn by observing somebody else or listening to somebody else without a purposeful effort to connect these sensory experiences to what they already know and to actively test new ideas. This principle is also known as active learning. 2. Learning is a social process that involves people sharing, debating, and testing their ideas in interaction with others. This principle is often referred to as group work. Copyright © 2019, 2014 Pearson Education, Inc. All Rights Reserved.

1. 1 What Is Physics? (4 of 8) The search for rules • Physicists search for general rules, or laws, to understand the behavior of the world they live in. • The meaning of the word law in physics is somewhat different than in daily usage; law means a causal mathematical relationship between variables. • Causal relations show change in one quantity affects the change in another quantity, but does not explain why causation occurs. • Laws are temporary in nature; new findings lead to modifications or sometimes abondonement.

1. 2 Modeling (1 of 5) • Physicists study how the complex world works. • The investigation into some aspect of that world often begins with a simplified version. • These simplified representations, called models, are useful in understanding any complex physical phenomena. • Physics begin with simple models and then add complexity as needed to investigate more detailed aspects of the phenomena. • Example of how one moves their body as one walks – – Back foot movement Arm movement Trunk movement Head movement Copyright © 2019, 2014 Pearson Education, Inc.

1. 2 Modeling (2 of 5) A simplified object • To simplify real objects, physicists often neglect both the dimensions of objects (their sizes) and their structures (the different parts) and instead regard them as single pointlike objects.

1. 2 Modeling (3 of 5) A simplified object Point-like object A point-like object is a simplified representation of a real object. As a rule of thumb, you can model a real object as a point-like object when one of the following two conditions is met: (a) when all of its parts move in the same way, or (b) when the object is much smaller than the other relevant lengths in the situation. The same object can be modeled as a point-like object in some situations but not in others. Copyright © 2019, 2014 Pearson Education, Inc. All Rights Reserved.

1. 2 Modeling (4 of 5) Modeling • The process that we followed to decide when a real object could be considered a point-like object is an example of what is called modeling. • In addition to simplifying the objects that they study, scientists simplify the interactions between objects and also the processes that are occurring in the real world. • Scientists add complexity as their understanding grows. • Galileo Galilei is believed to be the first scientist to consciously model a phenomenon. – Ignored falling bodies' interaction with air when studying falling objects Copyright © 2019, 2014 Pearson Education, Inc.

The goal of these tables is to show you where physics concepts and mathematical models come from. When working with an Observational Experiment Table, first watch the video of the experiment. Then read the description of the experiment in the left column of the table and try to analyze it without looking at the rest of the table. After you are done, compare your analysis to the analysis in the right-hand column(s) of the table and see if you agree with the described patterns. Copyright © 2019, 2014 Pearson Education, Inc.
